Is there a reason?

My wife went to the doctor's today. This is a rare event in our world because she detests going to the doctor's. She discussed a number of things with her doctor which surprised me because she usually pretty tight lipped about issues pertaining to her. He doctor is now going to do some testing to see if there is a reason why my wife is not loosing weight despite extreme amounts of exercise and a reduced calorie diet. I honestly hope she gains some insight into what might be going on. She has considered crash diets that work in order to actually see the scale move downward. I don't want there to be something wrong with her but I also don't want to see her continue to be discouraged with her lack of progress. It would be nice if there were something she could do to kick start the scale moving downward.
